UNIX for Dummies Questions & Answers

My n00b question:

I am trying to write a script that I can place on a flash drive and then move from computer to computer and install a file, which is bundled with the script. (ie the script is at /Volumes/FlashDrive/Folder/Script, the file is at /Volumes/FlashDrive/Folder/File)

So far I have figured the
"${0}" will determine the ever-changing location of the script, but how can I use that (or something else, for that matter) to also determine the location of the file to be installed?

So far, I have something like this:

Code:

MYPATH=${0}
cp $MYPATH/file /Applications

With the obvious problem that "$MYPATH" includes the name of the running script after the directory in which it and the file are located.

Any help would be great, thanks!

The dirname command should help you.
